The Microflex Low Profile Boundary microphone is an ideal table microphone when minimal presence is of high priority. Perfect for meeting rooms, these microphones deliver exceptional sound pickup while barely being noticed. Choose from a selection of colors & pickup patterns for customized table installations Only 1.25 inch (3.8 cm) in diameter Cardioid, omni & bidirectional polar patterns Wide dynamic range & smooth frequency response Available in black, white & aluminum Bi-color status indicator available with -LED models Logic input for remote LED control Comm Shield Technology Type Condenser (electret bias) Frequency Response 50 to 17000 Hz Polar Pattern MX395/O: Omnidirectional MX395/C: Cardioid MX395/BI: Bidirectional Output Impedance EIA Rated at 150 Ohms (170 Ohms actual) Output Configuration Active balanced Sensitivity (at 1 k Hz, open circuit voltage) Cardioid: -35 d BV/ Pa (18 m V) Omnidirectional: -28 d BV/ Pa (42 m V) Bidirectional: -37 d BV/ Pa (14 m V) 1 Pascal=94 d B SPL Maximum SPL (1 k Hz at 1% THD, 1 kilohms load) Cardioid: 121 d B Omnidirectional: 114 d B Bidirectional: 123 d B Equivalent output Noise (A-weighted) Cardioid: 28 d B SPL Omnidirectional: 21 d B SPL Bidirectional: 29 d B SPL Signal-to-Noise Ratio (referenced at 94 d B SPL at 1 k Hz) Cardioid: 66 d B Omnidirectional: 73 d B Bidirectional: 65 d B Dynamic Range (1 kilohm load at 1 k Hz) Cardioid: 93 d B Omnidirectional: 93 d B Bidirectional: 94 d B Common Mode Rejection (10 Hz
